A very interesting thread and you seem to have two first class rifles there, well looked after.
As Lakey remarked here, sometime ago, PCPs are without souls. Yours is of exceptional power, however, so clearly it has a purpose, probably to shoot at much greater ranges than would be possible with a sub 12ft lbs rifle. On the other hand, anyone can hit the centre of the target with a PCP. Almost no skill is required if a rest is employed.
Once one gets to appreciate the engineering within the springer, I have found that it is difficult to revert to the pcp - and I am without much technical ability. The former stands out, head and shoulders over the latter. I have returned to the sport after many years and much prefer, these days, the springer. There is more satisfaction using it. In turn, I became so impressed with the abilities of the old BSA Standard, that I purchased last year a 1922 version, with which I am delighted. This is one of the best air rifles ever produced, in my view, and far exceeds many of the air rifles that were produced up until the late '70s and even beyond in some instances. That said, they all seem to be a little different, each with their own personalities, which one has to learn.
A number of people have already added scopes to these rifles. I have seen many photographs posted here, not least, from memory, in Edbear's magnificent collection - one or two of which, I recall, had scopes. Some, I suspect, had them fitted before WW2 but not in all instances. Despite the view of the purists, I see no reason why these rifles should not be improved. After all, they are continuously being tinkered with and improved, with new springs, pistons, washers and so on being fitted. Ideally, one would seek a period scope - they are available. In addition, one would have very carefully to engineer the fitting to ensure a tasteful and acceptable mount, probably with a recoil arrestor.
Doubtless advice is available here - the members are most helpful - and there might be those who read this thread who can advise how their scope has been fitted. Many are capable engineers. Certainly, there are some substantial collectors of these rifles, some with scopes.
Lakey, if he reads this, might have a view.
I would be most interested to know how you get on and what sort of groupings you can achieve with a scope.
